>>3809328Sucy modifies her protection spell.
Every day, she removes an ounce of protection from Diana.
On day one, Diana notices an odor, but can't pinpoint it.
On day two, the odor gets a tiny bit stronger.
Every day, the funk increases.
After one week, Diana figures out that it's Sucy. She believes the protection spell is weakening, yet nobody else seems affected by it.
Sucy keeps decreasing protection from Diana, slowly altering her psyche.
After one month, Diana comes to class, obviously wearing the same shirt as the previous day.
Sucy smirks.
It's working.
